REPEATER OR MAGAZINE FUSE.

Application filed May 24, 1921.

To all whom t may concern Be it known that we, HENRY I. Drums, andJosErH B. HILL, both citizens of the United States, residing,respectively, at Millvale and Bellevue, both in Allegheny' County, inthe State of Pennsylvania, have invented a new and useful Improvement inRepeater or Magazine Fuses, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings, inwhich:

Figure 1 is a side elevation of a fuse embodying our invention;

Figure 2 is a section on the line II-Il oi? Figure 1; and

Figures 3 and 4 are sections, taken, respectively, on the lines III-IIIand lV-IV of Figure 2.

Our invention has relation to improvements in fuses, and moreparticularly fuses of the magazine or repeater type, in which there area plurality of fuse members adapted to be successively brought into useasa fuse member previously in use becomes destroyed.

The object of our invention is to provide a fuse of this character whichwill be more simple in its construction and more convenient in itsaction than other devices ot this character with which we are familiar.

The nature of our invention will be best understood by reference to theaccompanying drawings, in which we have shown a preferred embodimentthereof, which will now be described, it being premised, however, thatvarious changes may be made in the details of construction, arrangementand combination of the various parts without departing from the spiritand scope oi' our invention as defined in the appended claims.

In these drawings the numeral 2 designates a fuse block or carrier,which is shown as of generally cylindrical form, and which is of somesuitable insulating material, such as porcelain. It is provided at itsrespective ends with terminal members 3 and :l: ot' conducting material,and which are in the torm of screw caps which can be read- 0 il)7screwed upon the threaded end portions at' the carrier.

5 designates the fuse members, which are removably seated in spacedrelation on the carrier. In the particular device shown,

Serial No. 472,186.

cess 7 in the end of the carrier and also mak-` ing contact with oneofthe terminals 3 or 4. The inner end of each fuse section is bent, asindicated at 8, and is engaged with a. recess 9 at the central portionof the ca rrier. Thetwo sets ot recesses 9 are separated from each otherby the integral wall 10 of the porcelain body. The sections of the fusemembers extend through the apertures 11 `formed in said body. Theexternal portion of the body is cut away centrally, as indicated at 12,adjacent to the inner ends of the sections of the fuse members. A sleeve13 is rotatably mounted on the carrierover the opening formed by thiscutaway poition, being held in place by an inturned lip 15 at one end,which engages with the shoulder 16 of the carrier, and also by a spring.dog'17l secured to the sleeve and adapted to snap `into any one of amember of spaced depressions 18 formed in the outer peripheral surface,of the carrier. Each of these depressions is preferably numbered, asindicated in Figure 1, so that it can be determined at a. glance justwhich fuse is in useand how many have been used up.

The sleeve is shown as consisting of an inner metal lining with an outercovering of some` suitable insulating material, such as fiber. .Theinner metallic lining of the sleeve has a cut and inwardly bent portion19 which acts as a brush or contact to span the adjacent inner endportions of the two fuse sections of one complete fuse member and thuscomplete the fuse.

The operation will be readily understood. lV hen any fuse member becomesdestroyed, the sleeve is rotated one step, thus bringing the nextpair offuse sections into operation. and so on until all of the fuse meml` bershave been used. The terminal caps 3 and et can then be unscrewed andremoved, together with the sleeve 13, and a new set of fuse sections canbe inserted.

The advantages ot our invention will be apparent to those familiar withdevices ot' this kind. It provides a magazine or ropeater fuse in whichthe i'use members are at all times in electrical Contact at both endswith the terminal members, but by reason of the divided character ofeach complete fuse member only that fuse is actively in circuit which isengaged by the contact device of the rotatable sleeve. This sleeve formsa very simple and convenientmeans of making contact'between theseparated sections of the fuse members and of shifting from one tusemember to another. The device is thus free of complicated contact part-s'of ya. character likely to become deranged and inoperative in use.

We claim:

l. A repeater or magazine fuse comprising a carrier having a pluralityor" fuse mernbers, each of said fuse members being formed of twoseparated sections, and a movable contact device for spanning the gapbetween the sections of any 'fuse member, substantially as described. vY

2. A repeater or magazine fuse compr1sing a carrier of insulatingmaterial having removable terminal members at its ends, and apluralityof fuse members removably seated in spaced relation on said carrier,each of said fuse members being termed in two sections, each sectionbeing in contact with one of the terminals and the two sections havingseparated end portions, together with a contact device adapted to spanthe se`parated end portions ot each fuse member and to be moved from onefuse member to another, substantially as described.

3. A repeateror magazine fuse comprising a carrier of insulatingmaterial, a terminal member removably engaged with each end portion ofthe carrier, said carrier having a plurality oi spaced seats tor Jfuseele ments, a plurality ot fuse elements removably engaged with saidseats, each of said elements being formed in two sections, each of saidsections being in contact with one of the terminals at one end andhaving their opposite ends separated from each other, and a sleevemember rotatably mounted on the carrier and having a contact deviceadapted to span the gap between the ends of the sections ot any one ofthe fuse elements, substantially as described.

Ll. A repeater or magazine fuse comprising a carrier of insulatingmaterial, a terminal member of conducting material removably engagedwith each end of the carrier, said carrier having a plurality ot seatsfor fuse elements and being cut away exteriorly at an intermediateportion, a plurality of fuse elements removably engaged wit-h the seatsof said carrier, each of said fuse elements being formed ot two sectionsand each section having one of its end portions in electrical contactwith one ot the terminal members, the opposite ends of said membersbeing separated from each other, and a sleeve rotatably mounted on thecarrier and over the cut-away portion thereof and having a contactdevice tor spanning the separated ends et the fuse sections,substantially as'described.
